actually i have worked out the question..but i doubt about my answer..can anyone help me to verify this question please..kindly please refer to the attached files whereby i attached questions as well as my workings also...i really need help please..thanks in advance ..if possible may i have the other answers also please...

well as final answer for the change in entropy i got it to be -6.70 J/K..(i could not attach more files because the max possible file to be attached is 3.)
